Hereinafter, embodiments of the present invention are described with reference to the accompanying drawings.In fig. 1 it is shown that the expression present invention The embodiment of the apparent condition of the cloth 1 of embodiment.In FIG, cloth 1 is as first direction On x direction continuously.Reference 5 represents is located at the elastic component within cloth, and shown in this figure The form of many male and fomale(M&F)s is defined by many elastic components 5.By the plurality of male and fomale(M&F), such as Fig. 2 institute Show, define many pleated portions 6.
As shown in Figure 4, Figure 5, cloth 1 is made up of laminated sheet 30, and this laminated sheet 30 includes having First threadiness sheet material 2 of gas, the most also there is the second threadiness sheet material 3 of breathability and between the Between one threadiness sheet material 2 and the second threadiness sheet material 3 and there is the fibrous material 4 of liquid diffusibility, and It is by by described first threadiness sheet material 2, described second threadiness sheet material 3 and described fibrous material 4 Stacking is got up.First threadiness sheet material 2 and the second threadiness sheet material 3 constitute the fibre with breathability Dimension layer, additionally, fibrous material 4 constitutes the fibrous layer with liquid diffusibility.So, laminated sheet 30 Define composite bed 31, this composite bed 31 be by the fibrous layer (breathability fibrous layer) with breathability and Having what the fibrous layer (liquid diffusibility fibrous layer) of liquid diffusibility was laminated, composite bed 31 includes Liquid diffusibility fibrous layer that first breathability fibrous layer is adjacent with this first breathability fibrous layer and should The second breathability fibrous layer these three layers that liquid diffusibility fibrous layer is adjacent.
First threadiness sheet material 2 and fibrous material 4 engage discontinuously across elastic component 5.Preferably, Joint between second threadiness sheet material 3 and fibrous material 4 is also the joint being interrupted.As described joint side Method, can use the methods such as bonding, thermal welding, ultrasonic bonding, but come from the viewpoint of operational ease See, it is preferred to use bonding.Hereinafter, illustrate that employing is bonding real as the present invention in the case of joint method Execute mode.
Preferably, in bonding as joint method, use hot-melt adhesive as bonding agent.With Under, illustrate to use hot-melt adhesive as the embodiment of the present invention in the case of bonding agent.By using Hot-melt adhesive and by second threadiness sheet material 3 and fibrous material 4 be joined together discontinuously time, such as Figure 14 institute Show, hot-melt adhesive is coated discontinuously fibrous material 4 (or, it is also possible to hot-melt adhesive is interrupted Coat second threadiness sheet material 3), the rwo stacking is got up thus carry out engage integration.Now, Formed between the second threadiness sheet material 3 and fibrous material 4 and there is no the non-bonded part 8 of adhesive linkage 7, by this Non-bonded part 8 forms space 9.Additionally, due to elastic component 5 is between the first threadiness sheet material 2 and undulation degree Between material 4, therefore, by first threadiness sheet material 2 and fibrous material 4 being entered at the position of elastic component 5 Row engages, thus the discontinuity carried out between the first threadiness sheet material 2 and fibrous material 4 combines.That is, as Shown in Figure 14, hot-melt adhesive is sprayed at and separates predetermined distance and arrange the elasticity of configuration abreast in many The side face of component 5, makes the elastic component 5 being coated with this hot-melt adhesive be positioned at the second threadiness sheet material 3 and fibre Between surface and the first threadiness sheet material 2 of the fibrous material 4 in the duplexer sheet material of dimension material 4, thus Elastic component 5 is sandwiched surface and the first threadiness sheet material 2 of fibrous material 4 in described duplexer sheet material Between stacking get up, and carry out engage integration.Phase between first threadiness sheet material 2 and fibrous material 4 Part in opposite, that there is not elastic component 5 becomes non-bonded part 8, forms sky by this non-bonded part 8 Between 9, this is illustrated the most especially.In fig. 15 it is shown that pass through non-adhesive in pleated portions 6 Portion 8 is formed with the form in space 9.So, by being formed the such structure in space 9 by non-bonded part 8, carry The various functions of evapotranspiring property of moisture, thermal diffusivity and the poisture-penetrability of high cloth 1.
As shown in Figure 4, in laminated sheet 30, define male and fomale(M&F) by composite bed 31, utilize this recessed Convex surface defines pleated portions 6.As shown in Figure 2, Figure 3, Figure 4, by the protuberance 6a on male and fomale(M&F) and recess 6b Form pleated portions 6, by being formed continuously protuberance 6a and recess 6b, thus constitute many pleated portions 6.
As the method forming the pleated portions 6 being made up of protuberance 6a and recess 6b, as described above, at cloth The inside configuration elastic component 5 of material 1.The linear elastic bodies with retractility can be used as elastic component 5 5a, is preferably used thread rubber as this linear elastic bodies 5a.Hereinafter, illustrate to use linear elastic bodies 5a As embodiment during elastic component 5.
As shown in Figure 1 and Figure 2, linear elastic bodies 5a be configured to the bearing of trend of its line for and laminated sheet 30 The identical direction of long side direction (being x direction in Fig. 1, Fig. 2), and many linear elastic bodies 5a separate Predetermined distance ground configured in parallel.That is, linear elastic bodies 5a laminated sheet 30 width (Fig. 1, For y direction in Fig. 2) it is provided with compartment of terrain and is configured with many, define many linear elastic bodies row.
As it is shown in figure 5, linear elastic bodies 5a is arranged between the first threadiness sheet material 2 and fibrous material 4 Position.In the present invention, it is possible at random set the radical of linear elastic bodies 5a of per unit area, because of This, it is also possible to arbitrarily set the interval each other of linear elastic bodies 5a in linear elastic bodies row.Here, Y direction (being different from the second direction of first direction) along Fig. 1 and Fig. 2 is extended to another from one end One pleated portions 6 of end is referred to as " string pleated portions ".On the pleated portions 6 x direction in Fig. 1 and Fig. 2 every Open predetermined distance and define many row.Here, by the composite bed 31 of pleated portions 6 and linear elastic bodies 5a Between junction be referred to as pleated portions supporting-point.As mentioned above, it is possible at random set per unit area The radical of linear elastic bodies 5a, if increasing the radical of linear elastic bodies 5a thus reducing linear elastic bodies 5a Interval each other, then the quantity of the pleated portions supporting-point in string pleated portions will increase, therefore, The protuberance 6a in string pleated portions 6 and recess 6b can be made to be formed as uniform shape and keep its shape Shape.Thus pleated portions 6 will not be out of shape, therefore, from increasing the flexibility of cloth 1, evapotranspiring property of moisture, dissipating It is preferred from the viewpoint of hot and poisture-penetrability.From the point of view of this purport, it is preferred that pleated portions 6 that Interval between this i.e. protuberance 6a spacing each other is spaced apart 2mm～7mm.This protuberance 6a each other it Between spacing interval more preferably 3.00mm～6.25mm.By reducing between protuberance 6a spacing each other Every, it is possible to form the fold that texture is careful, therefore, it is possible to aesthetic appeal, and, due to each fold Diminishing with the contact area of skin, therefore skin feel improves, and is additionally, since surface area and becomes big, therefore Improve the absorbability to antiperspirant etc..On the other hand, it is spaced by enlarged boss 6a spacing each other, Can moderately suppress the elastic force of thread rubber, it is possible to reduce manufacturing cost.
Here, explanation uses thread rubber as linear elastic bodies 5a and to use hot-melt adhesive as bonding Agent manufactures an example of the manufacture method of the cloth 1 of the present invention.As aftermentioned, paper material be preferably used and make For fibrous material 4, and non-woven fabrics is preferably used respectively as first threadiness sheet material the 2, second fibrous pieces Material 3, therefore, by use paper material as fibrous material 4, and uses non-woven fabrics respectively as the first fiber The situation of shape sheet material the 2, second threadiness sheet material 3, as example, illustrates the manufacture method of the cloth 1 of the present invention. Here, the non-woven fabrics that will act as the first threadiness sheet material 2 is referred to as the first nonwoven fabric sheet, will act as second fine The non-woven fabrics of dimension shape sheet material 3 is referred to as the second nonwoven fabric sheet.
First, the paper material as fibrous material 4 is pulled out from take-up roll.Formed in this paper material in advance Printing layer 4a (with reference to Fig. 4, Figure 14).Make the paper material being drawn out through knurling rolls, press between the rolls This paper material, thus carry out mechanical soft sofening treatment.This mechanical soft sofening treatment both can be The embossing using flat-roll processes or can also be used in the nip roller on roll surface with multiple projection The embossing of (Japanese: body closes せ ロ Le) processes.In the embossing of the latter processes, can be in paper material The many trickle holes of upper formation.Paper material after described embossing processes sprays hot-melt adhesive discontinuously. In addition it is also possible to use the machining beyond embossing processing.On the other hand, conduct is pulled out from take-up roll Second nonwoven fabric sheet of the second threadiness sheet material 3, makes this second nonwoven fabric sheet and is coated with hot melt adhesion The paper material of agent crimps through flat-roll, both stacking is got up and produces conjugant sheet material. In this conjugant sheet material, the second nonwoven fabric sheet and paper material engage discontinuously.
Thread rubber from the take-up roll pull-out many row winding many thread rubber with also column-shaped.Silk Shape rubber is drawn out when the pulling force being prescribed has stretched.To the thread rubber spraying heat being drawn out Fusible dose.In this case, spraying and adhesive bonding agent continuously in the total length of the length direction of thread rubber. Additionally, bonding agent to be coated the whole side face of thread rubber.On the other hand, conduct is pulled out from take-up roll First threadiness sheet material 2 the first nonwoven fabric sheet, by this first nonwoven fabric sheet with described conjugant sheet The mode that material is relative is sent, and supplies thread rubber so that be coated with the thread of bonding agent as described above Rubber is clamped between above-mentioned conjugant sheet material and the first nonwoven fabric sheet.In this case, thread rubber It is supplied between the surface of the paper material of conjugant sheet material and the first nonwoven fabric sheet.
Make thread rubber be sandwiched in the surface of paper material of conjugant sheet material and the first nonwoven fabric sheet it Between state under through flat-roll.By use flat-roll come to conjugant sheet material, thread rubber, First nonwoven fabric sheet crimps, thus carries out stacking integration.First nonwoven fabric sheet and paper material Being made by what thread rubber carried out engaging, therefore, both are bonded together discontinuously.So, produce Engaged discontinuously by the second nonwoven fabric sheet and paper material and the first nonwoven fabric sheet and paper material discontinuously The laminated sheet 30 engaged thus constitute.As required, make laminated sheet 30 through knurling rolls, carry out machine The soft sofening treatment of tool.By carrying out this process, it is possible to improve the flexibility of cloth 1 further.
Laminated sheet 30 owing to producing is strip size, therefore, carries out cutting so that laminated sheet 30 Long side direction (in Fig. 1, Fig. 2 for x direction) on the length that length dimension is regulation.Cut at this During, cut off the first nonwoven fabric sheet, the second nonwoven fabric sheet, paper material and thread rubber.Pass through The cut-out of thread rubber, thus the thread rubber under extended state frees and in restoring force from pulling force Effect under shrink.Under the effect of shrinkage stress at this moment, by the first nonwoven fabric sheet, second The composite bed 31 that nonwoven fabric sheet and paper material are constituted is acted on by power on the direction that length shortens, Therefore, composite bed 31 is formed male and fomale(M&F), is consequently formed pleated portions 6.So, manufacture has many pleats The cloth 1 in wrinkle portion 6.
Here, the structure of cloth 1 of the explanation present invention, linear elastic bodies 5a under the effect of restoring force in The state shunk i.e. unstretched condition, form many edges and the linear elastic bodies under this unstretched condition The long side direction (direction identical with the long side direction i.e. x direction of the laminated sheet 30 in Fig. 1, Fig. 2) of 5a Orthogonal direction (direction identical with the width i.e. y direction of the laminated sheet 30 in Fig. 1, Fig. 2) is prolonged The pleated portions 6 stretched, is formed with pleated portions row in a pattern at laminated sheet 30.

The weight per unit area of the paper material constituting fibrous material 4 is preferably 7g/m2～50g/m2.If unit Area weight is less than 7g/m2, then when dressing the disposable fibrous product being made up of the cloth 1 of the present invention, It is difficult to obtain good wearing feeling, evapotranspires performance in addition, it is difficult to make this product have sufficient moisture and dissipate Heat energy, and the intensity of cloth 1 is the most insufficient.If weight per unit area is more than 50g/m2, then the thickness of cloth Spending thickening, above-mentioned wearing feeling is also deteriorated, and described moisture evapotranspires performance and heat dispersion also reduces.This Outward, owing to product thickness is the most thickening, therefore, carry out being difficult to packaging during product packaging.Paper material Weight per unit area is more preferably 10g/m2～30g/m2。
As the paper material constituting fibrous material 4, it is also possible to use chromatics paper, by so constituting paper wood Material, using the teaching of the invention it is possible to provide the cloth 1 that taste is higher.
Preferably, the paper material of composition fibrous material 4 is made to have softness by the soft sofening treatment of mechanicalness Structure.Use embossing as mechanical soft sofening treatment to process.As being used in what embossing processed Knurling rolls, use a pair knurling rolls forming many projections on roll surface.When using described pressure When flower roller is embossed process, while many trickle holes being formed in paper material, make the tissue of paper It is brittle so that paper material has flexibility.Described hole both can be circular hole, it is also possible to be wire Hole, it is also possible to be the hole of slit-shaped.Not perforate in paper material, but arrange by many concavo-convex realizations Matsurface, also thus is able to similarly make paper material have flexibility.
The knurling rolls being used in embossing process are not limited to have bossed roller, it is possible to use do not have projection And there is the pair of planar roll of smooth roll surface.Make paper material between flat-roll, between the rolls Pressing paper material, thus carry out the embrittlement of paper tissue.That is, even if not carrying out punching process, utilize between roller Paper tissue also can be made brittle by pressure.Process as the embossing for making paper material have soft structure, The embossing carried out by having the realization of bossed knurling rolls on roll surface can also be combined process and by flat-roll The embossing realized processes.
Paper material is made to have soft structure due to above-mentioned, it is thus possible to make cloth 1 entirety also have foot Enough flexibilities, therefore, when dressing the disposable fibrous product being made up of this cloth 1, wearing feeling is good. That is, user will be allowed to feel unnatural because paper material is used as the material of described product, can make The gratification that user is brought by soft wearing feeling.
Construct by giving paper material softness, following such effect can be produced.That is, if as undulation degree The paper material of material 4 is soft structure, then the entirety of laminated sheet 30 becomes soft structure and is easily deformed, because of This, when forming pleated portions 6 at the shrinkage stress because of linear elastic bodies 5a, laminated sheet 30 is easily deformed, The uniform pleated portions of shape 6 of protuberance 6a and recess 6b can be formed.By forming protuberance 6a and recess 6b The uniform pleated portions of shape 6, also increase cloth 1 flexibility on the whole, be made up of once cloth 1 Property fiber product in, it is possible to give the wearing feeling that user is soft further.It addition, by giving paper wood Material flexibility, it is possible to give the whole soft sense of cloth 1.
It addition, utilize brittle process of the paper tissue that described embossing realizes to have tax further as described later Give the effect of evapotranspiring property of moisture, thermal diffusivity and the poisture-penetrability of cloth 1 excellence.
As it has been described above, by when engaging between the second threadiness sheet material 3 and fibrous material 4, heat is preferably used Fusible dose.As hot-melt adhesive, can list EVA (ethylene-vinyl acetate copolymer) be, PO (polyolefin) is, PA (polyamide) is, SR (organosilicon synthetic rubber) is, ACR (acrylic acid) System, PUR (polyurethane, moisture-curable) such as are at the bonding agent, both can use one of which bonding agent, Two or more above-mentioned bonding agents can also be applied in combination.As by the second threadiness sheet material 3 and undulation degree The bonding agent used during material 4 joint, in addition to described hot-melt adhesive, it is also possible to use organic solvent system Bonding agent, water soluble adhesive etc..
As the mode that the second threadiness sheet material 3 and fibrous material 4 are engaged, can be at both contact surfaces Whole front surface coating adhesive, but be coated with the most discontinuously.With whole phase of coating Ratio, during coating, cloth 1 limbers up discontinuously, and evapotranspiring property of moisture, thermal diffusivity and the moisture-inhibiting of cloth 1 Property becomes good.As the coating process of the interruption of bonding agent, can list wire, point-like, strip, The coating processes such as helical form, bulk, pattern-like, both can use a kind of method in these coating processes, Or multiple method can also be applied in combination.
By coating adhesive discontinuously, thus formed between the second threadiness sheet material 3 and fibrous material 4 Non-bonded part 8, but relative to the area of the second threadiness sheet material 3, the area ratio of non-bonded part 8 is preferably 5%～85%, more preferably 10%～80%, more preferably 30%～75%.If the face of non-bonded part 8 Within the above range, then the flexibility of cloth 1, evapotranspiring property of moisture, thermal diffusivity and poisture-penetrability are excellent for long-pending ratio Different, the soft sense of the entirety of cloth 1 is the most excellent.Thus, it is possible to say, as long as the coating weight of bonding agent reaches It is obtained in that amount required during the bond strength of regulation, preferably coating weight are the fewest.
As it has been described above, it is the long limit with laminated sheet 30 that linear elastic bodies 5a is configured to the bearing of trend of its line The direction that direction (being x direction in Fig. 1, Fig. 2) is identical, and linear elastic bodies 5a is at laminated sheet 30 Width (in Fig. 1, Fig. 2 for y direction) on be provided with compartment of terrain and be configured with many, define perhaps Many linear elastic bodies arrange.When many linear elastic bodies 5a are configured at laminated sheet 30, however it is not limited to will Each linear elastic bodies 5a configures abreast.Linear elastic bodies 5a shown in (a) of Fig. 6～(j) of Fig. 6 Configuration mode.
As the configuration mode of linear elastic bodies 5a, both can arrange abreast as shown in (a) of Fig. 6 Linear elastic bodies 5a of row linearity, it is also possible to flat as shown in (b) of Fig. 6 and (c) of Fig. 6 On all or part of of linear elastic bodies 5a of the linearity arranged, disconnection portion is set capablely, it is also possible to as With the curve of also column-shaped bent arrangement as shown in (d), (f) of Fig. 6 of Fig. 6 and (g) of Fig. 6 Linear elastic bodies 5a of shape, it is also possible to brokenly as shown in (e) of Fig. 6 and (j) of Fig. 6 The mode of arrangement arranges curvilinear linear elastic bodies 5a of waveform.Alternatively, it is also possible to such as (h) of Fig. 6 Linear elastic bodies 5a is arranged with mesh pattern with as shown in (i) of Fig. 6.Preferably, in many wire In the arrangement of elastomer 5a, each linear elastic bodies 5a has identical expansion and contraction but it also may combination has Linear elastic bodies 5a of different expansion and contractions.It addition, elastic component 5 is not limited to string-like form, it is also possible to Use is provided with many holes or otch thus has the sheet elastomers of the breathability of regulation, and this is omitted diagram. As such sheet elastomers, can use the rubber based on carbamate, silicon and sky The elastomeric materials such as right rubber are as raw-material sheet elastomers.In the present invention, it is preferred that use Linear elastic bodies 5a of string-like form is as elastic component 5.
It is engaged in the mode between the first threadiness sheet material 2 and fibrous material 4, both as linear elastic bodies 5a Can be to utilize the bonding agent being coated in linear elastic bodies 5a that linear elastic bodies 5a is engaged in the first fibre Between dimension shape sheet material 2 and fibrous material 4, or can also be to utilize to be coated on the first threadiness sheet material 2 and fibre The bonding agent of dimension material 4 linear elastic bodies 5a is engaged in the first threadiness sheet material 2 and fibrous material 4 it Between.As described bonding agent, it is possible to use with above-mentioned for the second threadiness sheet material 3 and fibrous material 4 Between the same bonding agent of the bonding agent of joint.Preferably, use hot-melt adhesive as bonding agent.
Hot-melt adhesive is sprayed at the side face of each linear elastic bodies 5a, and the hot-melt adhesive after this coating exists Linear elastic bodies 5a is clipped under the state between the first threadiness sheet material 2 and fibrous material 4 and this three is connect Altogether, therefore, it is not necessary to be coated with hot-melt adhesive on the first threadiness sheet material 2 and fibrous material 4 respectively. Furthermore it is possible to not coating adhesive in linear elastic bodies 5a, but at the first threadiness sheet material 2 and fiber The respective contact opposite face coating adhesive contacted with linear elastic bodies 5a of material 4.
As described above, the hot-melt adhesive of the side face being sprayed at each linear elastic bodies 5a is utilized, with by line This three has been engaged by the state that shape elastomer 5a is clipped between the first threadiness sheet material 2 and fibrous material 4 Come, but under this engagement state, in the layer of the part meeting infiltrated fiber material 4 of hot-melt adhesive, thus Define bonding agent osmosizing portion Z as shown in Figure 16.Due to this bonding agent osmosizing portion Z and linear elastic bodies The hot-melt adhesive of 5a side face is integrally forming, and therefore, this bonding agent osmosizing portion Z is at linear elastic bodies 5a and fibre Playing fixation in joint between dimension material 4, strengthening utilizes the wire that hot-melt adhesive realizes further Joint between elastomer 5a and fibrous material 4.So, fibrous material 4 defines utilize bonding agent The fixture construction realized.Thus, it is possible to provide following such cloth 1, it may be assumed that even if having to wire bullet The less such advantage of bond strength also being able to obtain regulation of the coating weight of the bonding agent of gonosome 5a coating, It addition, the bulk strength of cloth 1 improves, firmness is higher.It addition, in figure 16, eliminate applying The diagram of the bonding agent between the second threadiness sheet material 3 and fibrous material 4.
Following bad problem is there is, i.e. use bonding agent in the cloth of conventional disposable fibrous product When engaging non-woven fabrics and non-woven fabrics, bonding agent can be exuded to design on fabric surface through the fibre gap of non-woven fabrics, But for the cloth 1 of the present invention, comprise fibrous material owing to being formed with composite bed 31 and composite bed 31 4, therefore, bonding agent penetrates into fibrous material 4, thus has and be prevented from bonding agent and be exuded to cloth table The effect in face.
As it has been described above, in the manufacturing process of cloth 1, the laminated sheet 30 prepared continuously is cut, Thus obtain the product of given size length.Owing to being strip size, therefore carry out cutting so that lamination sheets Length dimension on the long side direction (for x direction in Fig. 1, Fig. 2) of material 30 is specific length.Carry out this When cutting, linear elastic bodies 5a is cut off, thus linear elastic bodies 5a under extended state solves from pulling force Release and shrink under the effect of restoring force.By shrinkage stress now, on composite bed 31 Formed male and fomale(M&F), here, linear elastic bodies 5a and first threadiness sheet material 2 between engaging force, wire In the case of engaging force between elastomer 5a and fibrous material 4 is less, can be in linear elastic bodies 5a and first Threadiness sheet material 2 between, peeling-off between linear elastic bodies 5a and fibrous material 4, shrinkage stress is not made For include utilizing including the articulate first threadiness sheet material 2 of this linear elastic bodies 5a and fibrous material 4 Composite bed 31, there is so-called " rubber depart from (Japanese: go system け) " such phenomenon.By In such " rubber disengaging ", the power in the direction that composite bed 31 will not be shortened along its length, therefore, Composite bed 31 is formed without male and fomale(M&F), thus causes being formed without the such situation of pleated portions 6.At this. As shown in figure 16, when being formed with the bonding agent osmosizing portion formed by hot-melt adhesive in the layer at fibrous material 4 During Z, the engaging force between fibrous material 4 and linear elastic bodies 5a becomes firmly, therefore, it is possible to prevent by line " rubber disengaging " is produced when shape elastomer 5a cuts off.

It is disposable fibrous that the cloth that the present invention of said structure is described and the cloth using the present invention are constituted The action effect of product.In the cloth 1 of the present invention, owing to being formed with pleated portions 6 at laminated sheet 30, Therefore, have the effect that the skin with health contacts softness, it is possible to make whole cloth play softness Property.
It addition, in laminated sheet 30, include that as stacking constituent material first with breathability is fine Dimension shape sheet material 2, there is the second threadiness sheet material 3 of breathability equally, there is the undulation degree of liquid diffusibility Material 4, additionally, the fibrous layer with breathability is disposed adjacent to each other with the fibrous layer with liquid diffusibility. So, by have breathability fibrous layer and have liquid diffusibility fibrous layer stacking adjacent to each other and The composite bed 31 become is formed at laminated sheet 30.The disposable fibrous product being made up of the cloth 1 of the present invention When wearing this product in the way of such as making the first threadiness sheet material 2 be connected to the skin side of health, health institute The antiperspirant produced can be absorbed in the layer of fibrous material 4 through the first threadiness sheet material 2, and antiperspirant is at this undulation degree The layer internal diffusion of material 4.Through diffusion, in layer, the most scattered antiperspirant is steamed through the second threadiness sheet material 3 It is scattered to outside.Thus, antiperspirant will not be stranded in the position contacted with cloth partly, and it is right to carry out efficiently Evapotranspiring of antiperspirant.
That is, in the composite bed 31 of laminated sheet 30, air permeability layer and liquid diffusibility functional layer are Being disposed adjacent, therefore, air permeability layer and liquid diffusibility functional layer play and interact, and pass through This interaction, makes the efficiency of evapotranspiring of antiperspirant suddenly increase severely.That is, lead to due to the moisture in air permeability layer Water Pathways in road and liquid diffusibility functional layer is adjacent and continuous, therefore, the absorption efficiency of antiperspirant, Drying efficiency is very big.Further, since the pleated portions 6 being formed at laminated sheet 30 is configured to have by compound Layer 31 is formed with the pleated portions of the structure of male and fomale(M&F), the therefore air permeability layer in composite bed 31 and liquid Diffusibility functional layer becomes concavo-convex form, thus becomes the state that surface area is bigger.Its result, enters One step improves the efficiency of evapotranspiring of the antiperspirant from composite bed 31.
The cloth 1 of the present invention can distribute the heat from body diverging efficiently, and thermal diffusivity is excellent.From health The heat dissipated is delivered in the layer of fibrous material 4 through the first threadiness sheet material 2, and heat is at this fibrous material 4 Layer internal diffusion.Fibrous material 4 has the character of liquid diffusibility, by having liquid diffusibility, moreover it is possible to Play heat diffusivity simultaneously.The heat being dispersed in widely by diffusion in layer is through the second threadiness sheet material 3 It is dispersed into outside.Thus, heat will not be stranded between health and cloth 1, can carry out distributing of heat efficiently. The reason of the thermal diffusivity that the cloth 1 of the present invention can play such excellence is: with the evapotranspiring property of described antiperspirant Effect situation similarly, laminated sheet 30 have by have breathability fibrous layer and have liquid expand Dissipate the composite bed 31 that the fibrous layer of property is laminated adjacent to each other, in this composite bed 31, breathability merit Ergosphere and liquid diffusibility functional layer play and interact.
Further, the poisture-penetrability of the cloth 1 of the present invention is the most excellent.Generally, just by multiple constituent material stackings Laminated sheet for, there is the lowest tendency of quantity poisture-penetrability the most at most constituting layer.With by two The common laminated sheet that individual fibrous pieces material is laminated is compared, and in the present invention, addition of undulation degree Expecting 4 such material layers, therefore, the quantity constituting layer is more.But, the conventional cloth good with poisture-penetrability Material is compared, and the poisture-penetrability of the cloth 1 of the present invention does not the most reduce, it is possible to play good with poisture-penetrability conventional The poisture-penetrability that cloth is equal.Although it can be said that the quantity constituting layer increases but is able to maintain that good moisture-inhibiting Property this point be the peculiar effect of the present invention.It is believed that the reason that can play such effect is: with institute Stating similarly, laminated sheet 30 has by having the fibrous layer of breathability and having the fiber of liquid diffusibility The composite bed 31 that layer is laminated adjacent to each other, in this composite bed 31, air permeability layer and liquid Diffusibility functional layer plays and interacts.
In the cloth 1 of the present invention, when fibrous material 4 is paper material, if paper material is carried out above-mentioned Embossing process and carry out the brittle process of paper tissue, then can increase air permeability layer and liquid further The interaction of bulk diffusion sexual function, it is possible to improve evapotranspiring property of moisture, thermal diffusivity and poisture-penetrability further.
It addition, in embodiments of the present invention, cloth 1 is implemented printing, it is possible to effective and high Show multiple design, information to effect.The cloth 1 of embodiment of the present invention can flexible utilization cloth itself Feel, and the overall soft sense of cloth, flexibility are excellent, it is possible to efficiently and effectively give various Function.Further, the cloth 1 of the present invention has the advantage that, i.e. can manufacture with low cost, system It is the easiest etc. to make.
